It turns out the reason for that first sleepless night is that when you should be in your deepest sleep, your brain's left hemisphere keeps watch instead, ready to wake you up if anything scary happens.
结果证明第一个无眠之夜的原因是，当你在沉睡的时候，你的大脑左半球仍在提防，如果有任何可怕的事情发生，随时准备唤醒你。
The researchers played random beeping sounds in volunteers' ears while they slept in an unfamiliar place. The volunteers were more likely to wake up when they heard the noise in their right ear which is connected to the left brain hemisphere than in their left ear.
